Hi, I am trying to use the jdbc drivers in a fairly simple applet in java 1.5.0_03-b07 under linux. However, I am having problems with both running from appletviewer and firefox. I can howerver run an application and connect and retireve information. My init function looks like this: public void init() { String url = "jdbc:postgresql://server/dbase"; try { Class.forName("org.postgresql.Driver"); Properties props = new Properties(); props.setProperty("user","myname"); props.setProperty("password","secret"); Connection conn = DriverManager.getConnection(url, props); Statement st = conn.createStatement(); ResultSet rs = st.executeQuery(...some sql); ..... and so on As you can see this follows the info doc for JDBC pretty closely. As I said it works fine in an application. However, when I try to load it in appletviewer it throws the following exception: "Method CalledCaught SQL Exception: Something unusual has occured to cause the driver to fail. Please report this exception." It seems like some non-sql related function barfed up an exception. Anyways, no idea there. When I tried to run this within a page generated by CherryPy in firefox 2.0, it loads the applet in the background but then fails when it tries to perform Class.forName. Looking in my CherryPy log file I saw the following errors: "The path '/java/org/postgresql/driverconfig.properties' was not found." "The path '/java/org/postgresql/translation/messages.class' was not found." "The path '/java/org/postgresql/translation/messages.properties' was not found." "The path '/java/org/postgresql/translation/messages.properties_en.class' was not found." "The path '/java/org/postgresql/translation/messages.properties_en.properties' was not found." "The path '/java/org/postgresql/translation/messages.properties_en_US.class' was not found." "The path '/java/org/postgresql/translation/messages.properties_en_US.properties' was not found." What the heck? Its right none of those files do exist in the jar archive. I see a reference to driverconfig.properties when trying load default parameters... but I don't even see references to those other files anywhere in the source. I also tried putting everything in jar archive and loading that in the html with no effect. Please .... any ideas? I have no idea how to proceed. Thanks, Morgan Please
